UNITED STATES PATENT OFFICE.

ROBERT E. SHARP, OF CHICAGO, ILLINOIS, ASSIGNOR T0 LILLIAN R. SHARP,DOING BUSINESS AS PERFECT POWDER N 0 Drawing. Application filed DecemberMy invention relates to a rouge, such as that used for heightening thecolor of the skin, and it conslsts in the mixture hereinafter set forth.

Heretofore dry rouge (as distinguished from grease or paste rouge) hasbeen made by using water soluble or spirit soluble color, together witha dry powder, to give to the dry powder the shade required for variouscomplexions, and the manufacturers have always endeavored to make arouge so that it would appear-to the eye to be the same shade, whenapplied to the face, that it appeared in the box. This has compelled thedealers to carry a very large stock of the various shades of differentmanufacturers, in order to fit the many different complexions of theircustomers.

The ordinary dry rouge, being made of colored powder, will wash off orstreak, and therefore requires repeated applications. The color on theface of the user of the ordinary rouge is exactly the shade of thecolored powder, regardless of the complexion of the individual using it.This makes it quite an artistic undertaking for the woman to select ashade that will fit her complexion. i 7

An object of my invention is to provide a rouge which will; fit anycomplexion, from r the darkest brunette to the lightest blond.

A further object of my invention is to provide a rouge which-will notwash off except by the use of cold cream or soap.

A further object of my invention; is to provide'a roug gge whichv meetswith the natural oil of the face to. renderit effective.

Other objects and advantages will appear in the following'specification,and the novel features of the inventionwillappear in the appendedclaims. i y,

In carrying out my invention,- I-make-v use of a dry oil-soluble and"water-insoluble;

brilliant red pigment, such,-'for,, instance,

amidoazobenzol-B naphtol o-amidoazotoluol-B naphtol, listed as number"223 and 232, respectively, in Schultz on Dyestufl's, German edition1914:. The particles of this pigment are infinitesimally small. Withthis igment I mix a dry white powder, the'su stance of which is equallyfine and free from grit. The powder which I prefer is powdered silicathat has been air and water floated. Such powder is impal- PUFF 00., orCHICAGO, ILLINOIS.

pable, pure, and free from any oily or soapy substance.

In practice, I thoroughly mix six ounces of the pigment with twentypounds of the white powder. There is no change in the consistency of thedry oil-soluble pigment after it has been mixed. At first, the mixtureis white, but in a few days it changes to a faint lavender or orchidtint. I The reason for this appears to be that when the powder and thepigment are first mixed, the small particles of the color are notentirely distributed over the small particles of White powder, so thatthe characteristic color, i. e., white, is from the predominatingsurface of the white powder. In a few days the cohesive attraction ofthe small particles of pigment bring them together, thereby covering thesurface of the white powder and giving the latter a thin coating of thedry color, which, together with the white body of the silica, has alavender or an orchid tlnt.

It will be seen that with this powder there are two substances, bothextremely fine, the particles of which are held together by cohesiveattraction, but neither of which has any chemical affinity for theother. The result is that if this powder is rubbed on the face, thesmall particles of the dry pigment are instantly soluble in the thinfilm of oil that covers the skin, and the small particles of dry powderare brushed on" of the skin. Therefore the thin film of oil covering theskin has been colored a bri]liant're l.- This color is so exceedinglythin that the light rays reflected from the skin show just a brighteningof the skin, without changing the complexion.

Now since the color of an object is not a property of the object, butrather depends upon the light coming from the object, it

v will be apparent that the color which results from the application ofmy improved rouge to the skin depends upon the complexion of the skin,so that although two persons might apply the rouge in the same manner,the resulting color to the portions to which the rouge has been appliedmay be quite different. This is not true of the application of theordinary rouge, because the ordinary rouge is an opaque powder, and therouge from the same box will have the same color on persons of differentcomplexions.

It will thus be seen that the rouge which forms the subject of thepresent invention really gives to the face a thin film, through whichthe light from the skin will pass, and which will give an effect ofheightened color, because of the thin film of red material.

As stated before, the ordinary powder will wash off. But the thin filmof red coloring matter, which is oil-soluble, will not wash off, exceptby the use of an oil removing material, such as cold cream or soap. Thisobviates ,the necessity of frequent applications, such as are necessarywith the ordinary rouge, and such as can often he observed.

While I have specified a toluol and beta naphthol red as the preferredoil-soluble pig- -ment, and powdered silica as the preferred whitepowder, other oil-soluble pigments, such as vegetable red or other whitepowders, such as chalk or zinc stearate, may be used to obtain a fairresult. contemplate the use of any ingredients which will attain theresults set forth, i. e., the production of a rouge. which will fit Ithereforeany complexion, owing to the solubility of the color and thethin film which forms on the skin, and through which the color of theskin is visible.

I claim: x

1. A face rouge comprising a mixture of an oil-soluble red pigment whichis insoluble in water, and a dry white inert powder.

2. A face rouge, comprising a white powder consisting of fine particles,the particles of said white powder having a relatively thin roating ofan oil-soluble. pigment which is insoluble in water.

3. A face rouge. comprising a mixture of an oil-soluble red pigmentinsoluble in water, and a dry white powder in substantially theproportions of six ounces by weight of the pigment to twenty pounds byweight of the white powder. I

4. A face rouge, comprising a mixture of an oil-soluble red pigmentwhich is insoluble in water, and powdered silica.
